i have a slightly different and shorter idea
My personal theory is as follows-
Halo isnt just a weapon, it can bend space and time, it can go back and fourth through time to prehaps escape the Flood, and the Forerunners are humans from the future that is why 343 Guilty Spark reconized the Master Chief in Halo 1, and they're humans maby also because they evolved on Earth as evidence of this Forerunner artifact or a.k.a. "The Arch" left behind, and mentioned in the end of halo 2 by 343, also maby Gavemind may have told Cortana that Halo could use time-travel, so she now understands what happens from to loggs of Halo or somthing, of what happened thats why in this she says, "I know you, your past, your future." And how she is able to say, "This is how the world ends." In addition I have noticed that Forerunner engineering has taken a similar path to our own.
In the end Earth is destroyed and the Chief somehow escapes, as usual, frees Cortana, uses Halo's time-travel technology (with Cortana's help) to go back and save earth by useing High Charity to help defend against the Covenanat.
And so u know i just came up wit this idea by watching the halo 3 E3.
